Summary

Description
English: Portion of a transverse section of Mesostoma ehrenbergii: The epidermis (E) consists of cells divided into an outer and inner zone, the latter containing rhabdites (Rb); the cilia (Ci) are thickened about the middle of their length. Below the epidermis is the basement-membrane (BM), a layer of circular muscles (C) and of longitudinal ones (L). Below this again is the mesenchyma (M), made up of branched cells and dorso-ventral muscle-fibres (DM). The mesenchymatous glands (Rmc) are producing rhammites (Rm) which pass outwards.
